Well The LMO (tube type) in my SB-101 was made by TRW(stamped on the
case) , and so is the solid state LMO in my SB-102. The solid state
unit doesn't have any FETs in in just 2N706 transistors with a single
RCA 40080 output transistor.
It was also made by TRW. (the schematic for the solid state LMO is
available at bama.sbc.edu and it's mirror site).

Does anyone have the schematic of the Tube LMO?
